Build instruction

Instructions below assume you use Ubtuntu22

Prerequisites

sudo apt install cmake clang ninja-build -y
pip3 install --user conan

Build

mkdir build && cd build
cmake -DCMAKE_BUILD_TYPE=Debug            \
      -DCMAKE_C_COMPILER=clang            \
      -DCMAKE_CXX_COMPILER=clang++        \
      -DCMAKE_EXPORT_COMPILE_COMMANDS=YES \
      -DJCC_USE_ASAN=ON                   \
      -GNinja ../ && ninja

-DJCC_USE_ASAN=ON means enable the address sanitizer, which might be helpful to catch some memory bugs.

Run tests

ninja test

Usage

Note JCC is still in the very early stage, so don't expected it can handle everything correctly :)

  • Dump the AST tree of the program.
./jcc test.c --ast-dump # Note you can only pass the flag in the end!
  • Generate the assembly.
./jcc test.c # It will produce a.out
